This prospectus supplement is being filed to update and supplement the Prospectus with the information contained in our Current Report on Form 8-K filed with the U.S. Securities and Exchange Commission on February 10, 2023 (the “Current Report”). Accordingly, we have attached the Current Report to this prospectus supplement.

This prospectus supplement is not complete without the Prospectus. This prospectus supplement should be read in conjunction with the Prospectus, which is required to be delivered with this prospectus supplement. If there is any inconsistency between the information in the Prospectus and this prospectus supplement, you should rely on the information in this prospectus supplement.

Our shares of common stock, par value $0.0001 per share (the “Common Stock”) and warrants to purchase Common Stock (“Warrants”) are listed on the Nasdaq Stock Market under the symbols “PRST” and “PRSTW”, respectively. The last reported sales price of the Common Stock on February 9, 2023 was $4.11 per share and the last reported sales price of the Warrants was $0.14 per Warrant.

We are an “emerging growth company” and a “smaller reporting company” as such terms are defined under the federal securities laws and, as such, are subject to certain reduced public company reporting requirements.

Investing in our securities involves a high degree of risk. You should review carefully the risks and uncertainties described under the heading “Risk Factors” beginning on page 8 of the Prospectus, and under similar headings in any amendments or supplements to the Prospectus.

Neither the Securities and Exchange Commission nor any state securities commission has approved or disapproved of these securities or passed upon the adequacy or accuracy of the Prospectus. Any representation to the contrary is a criminal offense.

The date of this prospectus supplement is February 10, 2023.
